There is an old piscina showing that it once contained a chapel. Passing it we come along the Wharf to our starting-point, the Middle Tower, and so have completed the walk round the outside. And now starting from the Middle Tower and crossing a stone bridge over the Moat, which replaces a wooden drawbridge which gave entrance of old, but has been withdrawn now that there is no longer need of it, we are in the Inner Ward, and I shall do with this as with the Outer, and first walk round it on the outside. It is enclosed within a curtain wall, having twelve mural towers and a gatehouse. Its longest side faces the river, the east and west sides incline inwards, so that the north face is narrower than the base, and like the corresponding wall in the outer ballium, is broken by an obtuse angle, having like that a central salient. When we get to the inside we shall find that this Inner Ward is on a higher level than the Outer, some 15 or 20 feet. This may be partially owing to the earth excavated by Longchamp when the ditch was made being thrown up here. There is a clear passage between the Inner and Outer Ward, to which the ordinary visitor is not admitted. It is known as “The Casemates.” We first, by the courtesy of the authorities, walk round this and note the semicircles of the towers: on the west side, the Bell, Beauchamp and Devereux; on the north, Flint, Bowyer, Brick, Martin; on the east, Constable, Broad Arrow, Salt; on the south, Lanthorn, Wakefield, Bloody. Most of these will be noticed in turn. This passage round, which is now quite open, was formerly filled up with houses, warders’ residences and storehouses, which were removed in 1867. There are doorways along it into the outer wall, in which are lodgings for officials and chambers for stores. And now we make a yet further move, and pass within the wall, and so are in the heart of the Tower itself. The original entrance was through the Bloody Tower; it is so now for one division of visitors, but the Wakefield is made another entrance. Within, naturally, the prominent object in view as in historical interest is the Keep, the great White Tower of William the Conqueror. It stands on sloping ground, so that the north side basement is 25 feet higher than the south; quadrangular, 107 feet north and south by 118 east and west. The two western angles are square; that on the north-east has a round stone turret; the south wall terminates eastward in a bold half-round bow, marking the apse of the chapel. This keep is 90 feet high, composed of three floors, or four stages. The basement is below ground on the north, and on the ground level on the south. The walls are from 12 to 15 feet thick. The internal area is divided by a wall 10 feet thick, which rises from bottom to top, and so makes a separate smaller western and larger eastern portion. This last is again subdivided into two by another wall running east and west. The vault or subcrypt of
